12788	Slow USB2 speed	NagyGabor		"I want to use DVB adapters on guest VM. It works, channel scan and EPG are perfect, but the speed is too slow, it records only the 60% of the video stream. I have tried two adapters, and more guest OS, and the result is the same.

I have tried a USB HDD, for testing the speed. 
  - The HDD works on the host with 35 MByte/sec.
  - The HDD works on the guest in the read direction 20 Mbit/sec. (5% of USB2 speed)
  - The HDD works on the guest in the write direction 50 Mbit/sec. (10% of USB2 speed)

My host OS: openSUSE 13.1 64 bit, kernel: 3.11.10-7
VIRTUALBOX: 4.3.6r91406, ext. pack installed, USB2 checked
